I wouldn't use this if I were you. The last release was over 5 years ago, and there are multiple issues with the code - for instance, you can't even build it anymore if you're on CMake v4+. Basically, this project has been abandoned, and since you can no longer build it from source, you'd have to use the 5+ yr old binaries - which isn't advisable, especially in a production environment.

A better, actively-maintained alternative, is S6-overlay: https://github.com/just-containers/s6-overlay
